摘要:
A roller arrangement has a magnetic circuit that includes two rollers. The magnetic circuit consists of a cylindrical magnetic core, several poles axially distributed on the magnetic core, a cylindrical exciter and control windings arranged between these poles, a magnetic shell that encloses the whole circumference of one roller and is made of two parts separated by a ring-shaped secondary air gap, and a continuous magnetic shell in the axial direction arranged at the outer circumference of the other roller. When used to process webs of material in the textile, paper, plastic and metallurgical industries, this electromagnetic roller arrangement achieves high quality standards with a high productivity.

A nip roll is disclosed having an inner substantially rigid cylindrical member and an outer cover member of a generally incompressible substantially resilient material positioned about the inner member with reinforcing means embedded within the outer cover member having a tensile modulus greater than the modulus of the generally incompressible resilient material. The reinforcing means are so oriented with respect to the inner member that upon positioning the roll in nipped relation with a rigid roll which is externally driven, depending upon the direction of rotation, portions of the outer cover member are displaced and recoiled at the entrance and exit to the nip to provide resulting forces on web materials passed therethrough, the forces being controllable for treating such web materials. Depending upon the direction of rotation, the web material will either be compacted or elongated. A method is disclosed for producing the inventive nip roll.
摘要:
A system and method for cationization of textiles preferably starting with the dry raw greige tubular or open width goods that are made from either a cellulosic or cellulosic blended fabric. The system can include an inducer apparatus with chemical dosification system. In a preferred embodiment, the dry tubular goods are sent in a flat configuration to a first impregnation tank where it receives a multi-functional reaction fluid. After leaving the first impregnation tank, the now wet fabric is turned (when in a tubular width fabric form) by a turning unit and then sent to a second impregnation tank where it again is exposed to the multi-functional reaction fluid. The turning of the fabric causes the side edge positions of the flat tubular fabric to change its physics dynamics which allows for the multi-functional reaction fluid to be evenly applied to the entire fabric. Turning is not needed for open with fabric as it is flat, thus having only one dynamic when analyzed with physics.
摘要:
A device for applying a foamed treating material under pressure to a traveling sheet of relatively incompressible textile yarns. A foam applicator unit has a nozzle with a foam dispensing slot facing across one side of the traveling sheet of yarns. A drive roll faces the other side of the traveling sheet of yarns in tangential alignment with the foam dispensing slot. The roll has a resiliently compressible, soft rubber outer layer, which compresses to conform with the surface of the relatively incompressible yarns and presses the traveling sheet of yarns against the applicator surfaces leading to and away from the slot to prevent escape of foam and to prevent passage of foam between yarns to maintain uniform distribution of foam applied to the traveling sheet of yarns.
摘要:
There is disclosed a de-watering squeeze roll which is particularly intended for use in the watering operations in textile industries. The roll comprises a shaft, a relatively thick resilient sub-layer provided around the shaft, and a relatively thin resilient outer cover provided around the sub-layer. The sub-layer has a hardness greater than the hardness of the outer cover such that the sub-layer is formed from material having a Shore A hardness of between 85 and 105 whilst the outer cover is formed from material having a Shore A hardness of between 60 and 80.
